To (ZZZ whom it may concern Be it known that I, FRANK B. FREEMAN, acitizen oithe United States, and a resident of Dayton, in the county ofCampbell and State of Kentucky, have invented certain new and usefulImprovements in Machines for Reinforcing Insoles, of which the followingis a full, clear, and exact description, reference being had to. theaccompanying drawings, forming part of this specification. My mventionrelates tomachines for pressing in the canvas of reinforced insolesaround the upturned lip thereof. In machines of this character, it isvery desirable to have a light structure, silently running,

and easy to operate. Also in tucking the canvas around the upturned lipsof insoles, it is desirable to have not only one movable tool working upagainst the insole lip on the inside, but also to have a tool or toolsworkthe lip also. In machines oi this character, in the past it has beenfounddifiicult to provide the proper motion 'for the pressing-in toolswithout complicated mechanism, and it is desirable to simplify themethod of obtaining this motion.

Accordingly it is the ob ect of my invention to provide a machine of thecharacter mentioned which is light and silent running.

It is also an object of this invention to provide for the motion of thepressing tool by a simple vibrator in combination with a cain andspring, thereby greatly simplifying the mechanisms of the past.

Again it is the object of this invention to provide for oscillatingtools on the out said tools being actuated by the same device whichmoves the inner tool, the motion of these outer tools being such as tocooperate with the inner tool to accomplish the most effective andsmooth pressing down of the canvas around the inside lip.

These objects, and other advantages to be noted as the descriptionproceeds, I accomplish by that certain construction and, arfgrangementof parts to be hereinafter more specifically pointed out and claimed.

In the drawings, Figure 1 is a top plan view of the machine, with theoperating ting the edge of the insole and v the eccentric stud atmechanism removed. Fig. '2 is a side eleva tion thereof. Fig. 3 is anenlarged side elevation of the pressing-in tool. Fig. 4 is a perspectiveview of the lower plate for abutsame through the machine. Fig. 5 is adiagrammatic plan view showing the cooperating action of the variouspressing or tucking-in tools.

The base plate 1 of the machine is mounted on a standard 2 of suitablecharacter, which is preferably low so that the machine can be set up ona working table or bench. This base plate has a T-slot in its uppersurface; said plate having the cross portion 3 of the slot extendingthrough the plate from one side to the other, and the longitudinalportion 4: of the slot extending forwardly to the front of the plate. Onthis base plate is mounted the top plate 5 which supports a verticalshaft 6. This shaft is caused to rotate by any desired mechanism such asthe pulleys and belt 7 and 8 respectively, although this is not anessential part of my invention. 2

Mounted in the T-shaped slot between the two members is a T-shaped bar,having the lateral member 9 and the forwardly extending member 10.Thebar has a longitudinal slot 11 in it, and in this slot is set asquare block 12, having a hole 13 in it to receive the end of the shaft6. It can thus be seen that as the shaft rcvolves, the T-bar willbefcaused to reciprocate or vibrate in the slot. On an extension 14 fromthe top member is mounted an antifriction roller 15, which contacts withthe upper surf to of the T-bar through a slot in the said top member.Mol ted on the forwardly extending end of the bar member 10 is a block16, which has pivoted in a groove in its outer facethe pressing-in tool17. This block has alsoa transverse groove 18 in its rearward face,whereby it is mounted over the end of the T-bar, a removable screw 19 orthe like serving to secure the mounting.

A plate 20, having a cam edge 23'. is

guiding the mounted on top of the extension 14, and the roller 22 on theupper end of the tool 17 is spring-held against this edge by the spring23. This cam edge 21 slants from front to rear, and it is plain that asthe T bar memgage on' the inside of the lip 25 and press or .iron thecanvas 26 of th insole firmly into the crotch of the lip. Extending downfrom the rear, end of the tool holding member 16 is a'plate 27, havingasloping outer face 28 that engages the outside of the insole lip,

thereby backing up the movement of the claw 24and imparting the properslant to .the insole lip. There are thus two ironing or pressingmembers, one moving toward the other, and the canvas is not hammeredagainst the lip but is smoothed and ironed.

' into place.

Mounted on the under side of the base portion 1 of the machine is aplate 29, having a beveled edge 30, which extends out so as to contactwith the shoulders of the lip 25. This plate serves as a guide for theinsole through the machine, and is adjustably mountedby means of theslots 32 and the screws 33 for securing it to the machine base. Mountedon an arm34 extending forwardly from the standard to the machine is aour- -nal member 35. A shaft '36 extends through this journal member andis pushed upwardly in said member by a spring 37 housed within thejournal. At the lower end of this shaft are nuts 38, limiting the upwardmovement of the shaft and a hook 39 engaging with a foot treadle. On topof the shaft is a table 40, which extends up beneath the tool 17 ,andover, this table the insole is passed during the operations of themachine. Theplate 29 also extends out over this table, and it is obviousthat for inserting the work in the machine it is not necessides of thebase 1, and are held downwardly by springs 45. These rods bend inwardlyand downwardly at 46 to a position, one on one side and one on the otherside of the plate 27 of the tool holder. As the bar is vibrated, firstone and then the other of the rods 43 are tipped'at the rear. causingthe forward ends 46, 4(5,to come down and contact with the outer edge ofthe insole. just outside of the lip thereof.

The operation of the machineis then as follows. The T-bar is caused tovibrate by rotating the shaft 6, the table is lowered and an insole withcanvas aflZiXed to it is inserted at the side of the machine. The end 30of the plate 29 then serves as a guide at the edge of the insole. andthe plate 27 rests against the outside of the lip. The first member tostrike the insole in any sequence I of operations is the rod 43 nearestthe operator, which pulls the canvas well over the lip 'of the insole.The claw 24 then comes in against the inside of the insole, against theedge 28 of the plate 27 and simultaneouslythe other outside rod 43-comes down and cooperates with the claw in firmly tamping the canvasdown around the lip. The forward movement of the claw in a diagonal lineserves to feed the insole over thetable, and it is unnecessary toprovide means to revolve the table. The two outer tamping members servethe purpose of completely smoothing and pressing down the canvas on theoutside of the lip. For insoles having the lip at different positions infrom the edge of the leather portion of the insole, the plate 29 isto beshifted so as to change the position of the outer abutment.

Various modifications are possible in this machine Without departingfrom the-spirit of theinvention, and it'is not desired, by reason of theomission ofmention of such modifications, to limit the claims thatfollow beyond the full scope of equivalents,

where the wording ofthe claims does not said member, and means formaintaining one end of said tool against said abutment, to give itsworking end a diagonal movement toward the lip of an insole beingoperated upon.
